TOWING TIEDOWN HOOKS - FRONT /-- TIEDOWN HOOKS - REAR - TOWING Proper towing equipment is necessary to prevent dam- age to the vehicle. Laws and regulations applicable to vehicles in tow must always be observed. As a general rule, towed vehicles should be pulled with the driving wheels off the ground. If excessive damage or other conditions prevent towing the vehicle with the driving wheels off the ground, use wheel dollies. With either automatic or manual transmission. 1. Set the ignition switch in the ACC position; 2. Place the selector lever or shift lever in N (Neutral); 3. Release the parking brake. With manual transmission If the transmission, rear axle, and steering system are not damaged, the vehicle may be towed on all four wheels. If any of these components are damaged, use wheel dollies. With automatic transmission If excessive damage or other conditions prevent towing the vehicle with the driving wheels off the ground, use wheel dollies. If all four wheels are on the ground, the vehicle may be towed only forward. Don't exceed 56 kmlh {35 mph} and a distance of 56 km (35 miles); you could damage the transmission. If speed must exceed 56 kmlh (35 mph} or a towing dis- tance of 56 km (35 miles}, use one of these methods: Place the rear wheels on a dolly; Tow with the rear wheels off the ground; Disconnect the propeller shaft. If the transmission or rear axle is inoperative, two with the rear wheels off the ground. Caution Don't tow with sling-type equipment. This could damage your vehicle. Use wheel-lift or flatbed equipment. Caution Don't use the hook loops under the front for tow- ing. They are designed ONLY for tying down the vehicle when it's being transported. Using them for towing will damage the bumper. GI-I 9 Gartner Banana

ASSEMBLY 4. Apply silicone sealant to the shaded area shown in the figure. 5. Install the rear cover Tightening torque: 7.9-1 0.7 N.m (80-1 10 kgfem, 70-95.4 in-lbf) Oil Pump 1. Apply a small amount of clean engine oil to the lip of a new oil seal. 2. Push the oil seal slightly in by hand. 3. Using a pipe, press the oil seal in evenly until it is flush with the edge of the oil pump body. U' Note Oil seal outer diameter: 50.5mm (1.99 in} Oil seal inner diameter: 36.5mm (1.44 in) 4. Install the oil pump and a new gasket. Tightening torque: 19-25 N.m (1 -9-2.6 kgf-m, 14--18 ft-lbf) 5. Cut away the portion of the gasket that projects from the body toward the oil pan side.

B ASSEMBLY @ @ GREATER THAN @ @ 1. Assemble the SST so that depth L is as specified. Depth L: 18.3-18.9mm (0.721-0.744in) 2. Slide the valve seal onto the valve guide. 3. Set the SST against the valve seal. 4. Press the valve seal in until the SST contacts the cylin- der head. Valve and Valve Spring 1. lnstall the lower spring seat. 2. Install the valve. 3. lnstall the valve spring with the closer pitch toward the cylinder head. 4. lnstall the upper spring seat. 5. Compress the valve spring with the SST, and install the valve keepers. 6. Remove the SST. 7. Tap the end of the valve stem lightly two or three times with a plastic hammer to verify that the keepers are all fully seated. Gartner Banana

J TRANSMISSION Thrust lock washer 1. lnstall the synchronizer ring and 5th gear. 2. Insert the steel ball and thrust lock washer. 3. lnstall only the two 3.0mm I0.118 in) thick C-washers in the front mainshaft groove. 4. Push the C-washers fully toward 5th gear and measure the clearance between the thrust lock washer and C-washers. If the clearance is not as specified, select the proper thrust lock washer. Standard play: 0.1 -4.3mm {O.OO4--O.Ol2 in) Thrust lock washer thickness: 6.2mm (0.244 in), 6.4mm (0.252 in}, 6.5mm (0.256 in), 6.6mm (0.260 in} 5. lnstall the retaining ring. Mainshaft rear bearing 1. lnstall the rnainshaft rear bearing by using the SST, and fully seat it against the front C-washers. 2. lnstall the original C-washers and hold them with the retaining ring. 3. lnstall the washer and new snap ring. u 4. If the C-washers do not fit into the rear mainshaft groove, select the proper thickness C-washers. 5. Verify that both C-washers at one position are the same thickness. 6. With points @ through 0 pressed tightly together, mea- sure the clearance between the washer and snap ring. If the clearance is not as specified, select the proper C- washers. Standard play: 0-0.lmm (0-4.004 in) C-washer thickness: 2.9mm (0.114 in), 3.0mm (0,118 in), 3.1 mm (0.1 22 in), 3.2mm (0.1 26 in) Countershaft rear bearing lnstall the countershaft rear bearing onto the counter- shaft by using the SST.
